TECHNICAL FIELD

The present invention relates to a novel silicon compound characterizedby having a polymerization initiating ability for addition-polymerizablemonomers and a polymer obtained using the same.

RELATED ART

Polymers have come to be used in various fields not only as a generalpurpose structure-forming material but also as a value added typematerial having high-degree function and performance, and the importanceof producing high molecular materials under precise design isincreasing. Also in the field of organic-inorganic composite materialscontaining silsesquioxane as an inorganic component, it is veryimportant to create novel functional high molecular materials.

Polymers having distinct structures have to be synthesized in order toobtain such materials. A molecular property of a polymer and a propertythereof as a molecular aggregate can not precisely be analyzed if it isnot a polymer having a distinct structure, and therefore theperformances of the high molecular material can not be optimized so thatthey meet the object. However, almost all of conventionalorganic-inorganic composite materials have not contained organicpolymers having a controlled structure. A large part of them is obtainedby mechanically blending silsesquioxane with organic polymers, andtherefore it has been very difficult to control a structure thereof as amolecular aggregate of a complex.

Then, it has come to be tried to control a structure of a polymer byusing a polymerization initiator. It is disclose in Document 1 that anα-haloester group is a good initiator for styrene base monomers andmethacrylic acid base monomers in living radical polymerization.However, silsesquioxane derivatives having an α-haloester group have notso far been known up to now. It is disclose in Document 2 thatsilsesquioxane derivatives having a chloromethylphenethyl group arerelatively good initiators for styrene base monomers in living radicalpolymerization.

A² in Formula (1) is a group having an α-haloester group.

The group having an α-haloester group means a group havingα-halocarbonyloxy as an end group. An atom transfer radicalpolymerization method is known as a polymerization method using thisα-halocarbonyloxy group as an initiating group for radicalpolymerization. A polymerization catalyst used in this method is a metalcomplex comprising the eighth, ninth, tenth or eleventh element in theperiodic table as a central metal atom. It is known that the grouphaving α-halocarbonyloxy has an excellent polymerization initiatingability in this atom transfer radical polymerization. It is well knownas well that this polymerization is living fation.

That is, the compound (1) has an excellent polymerization initiatingability under the presence of a transition metal complex and cancontinue to maintain a living polymerization.

The compound (1) can initiate polymerization of all radicallypolymerizable monomers, and it can allow particularly styrene basederivatives to exhibit an excellent living polymerization.

The silicon compound of the present invention has α-halocarbonyloxy asan end group and therefore can be derived into a lot of derivatives byapplying various organic reactions. For example, the compound (1) can bederived into silsesquioxanes having an organic metal functional group byreacting it with lithium, magnesium or zinc. To be specific, thecompound (1) is reacted with zinc and derived into silsesquioxane havingan organic zinc functional group, and then aldehyde and ketone are addedthereto, whereby it can be converted into alcohols. That is,silsesquioxane having an organic zinc functional group is useful as anintermediate raw material used for a so-called Reformatsky reaction.

An α-halocarbonyloxy group in the compound (1) has a strongelectrophilicity, and therefore it can be converted into an amino groupand a mercapto group using various nucleophilic reagents. Further, thecompound (1) is treated with enamine to be converted into an imine salt,and this imine salt is hydrolyzed, whereby it can be converted intoketone. That is, the compound (1) is also useful as an intermediate rawmaterial used for a stork-enamine reaction. Silsesquioxane derivativeshaving various organic functional groups and polymerizable functionalgroups can be prepared as well by reacting the compound (1) withaliphatic or aromatic Grignard reagents. Accordingly, the siliconcompound of the present invention can be used not only as apolymerization initiator but also as an intermediate useful for variousorganic syntheses.

The preferred example of A¹ is a group represented by Formula (2):

in Formula (2), X¹ is halogen; R² is alkyl having a carbon atom numberof 1 to 20, aryl having a carbon atom number of 6 to 20 or aralkylhaving a carbon atom number of 7 to 20; R³ is hydrogen, alkyl having acarbon atom number of 1 to 20, aryl having a carbon atom number of 6 to20 or aralkyl having a carbon atom number of 7 to 20; Z¹ is alkylenehaving a carbon atom number of 1 to 20 or alkenylene having a carbonatom number of 3 to 8; and in these alkylene and alkenylene, optional—CH₂— may be substituted with —O—. The preferred example of Z¹ is—C₂H₄—O—C₃H₆—, —C₃H₆— or —C₂H₄—. The examples of halogen are chlorine,bromine and iodine. Chlorine and bromine are most preferred as aninitiating group for atom transfer radical polymerization.

Next, a production process for the silicon compound of the presentinvention shall be explained. The preferred raw material is a siliconcompound represented by Formula (3):

In Formula (3), R¹ has the same meaning as that of R¹ in Formula (1),and A² is an organic group having a hydroxyl group at an end.

This compound (3) used as a raw material is reacted with acid halide inwhich halogen is bonded to carbon in an α-position, whereby it can bederived into the compound (1). Then, the more preferred raw material inthe present invention is a silicon compound represented by Formula (4):

All R¹²'s in Formula (4) are the same group selected from alkyl having acarbon atom number of 1 to 8 in which optional hydrogens may besubstituted with fluorine and in which optional —CH₂— may be substitutedwith —O—, —CH═CH—, cycloalkylene or cycloalkenylene, phenyl in whichoptional hydrogens may be substituted with halogen, methyl or methoxy,non-substituted naphthyl and phenylalkyl constituted from phenyl inwhich optional hydrogens may be substituted with fluorine, alkyl havinga carbon atom number of 1 to 4, vinyl or methoxy and alkylene which hasa carbon atom number of 1 to 8 and in which optional —CH₂— may besubstituted with —O—.

Z¹ in Formula (4) is alkylene having a carbon atom number of 1 to 20 oralkenylene having a carbon atom number of 3 to 8. In these alkylene andalkenylene, optional —CH₂— may be substituted with —O—.

A synthetic route shown in the following scheme 1 and scheme 2 is one ofthe specific examples of a process for producing the compound (4). Thatis, a compound (A-1) is reacted with acetoxyethyltrichlorosilane at aroom temperature under the presence of triethylamine usingtetrahydrofuran as a solvent to prepare a compound B. Then, the compoundB is subjected to transesterification reaction in methanol under thepresence of a sulfuric acid catalyst, whereby a compound C havinghydroxyalkyl can be prepared. The compound (A-1) in the scheme 1 isobtained by obtaining polysilsesquioxane by hydrolyzing a siliconcompound having three hydrolyzable groups and then reacting it withmonovalent alkali metal hydroxide in tetrahydrofuran. The compound (A-1)is obtained as well by hydrolyzing a silicon compound having threehydrolyzable groups under the presence of alkali metal hydroxide in anoxygen-containing organic solvent and subjecting it to polycondensation.A compound (A-2) may be used in place of the compound (A-1). Thecompound (A-2) is described in Organometallics, 10, 2526-(1991). In thefollowing scheme, Ph is phenyl; THF is tetrahydrofuran; and TEA istriethylamine.

The compound (4) can be produced by a process of Feher et al. Theprocess of Feher et al is described in Chemical Communications(Cambridge, United Kingdom), 1289 to 1290 (1990). The compound (4) canbe produced by making use of the process of Feher et al for a part ofthe synthetic route.

One of the specific examples thereof shall be shown in a scheme 3 to ascheme 5.

That is, the compound (A-1) is reacted with vinyltrichlorosilane at aroom temperature under the presence of triethylamine usingtetrahydrofuran as a solvent to prepare a compound (D). Then, oneequivalent of trifluoromethanesulfonic acid is added to a vinyl group ofthe compound (D) to prepare a compound (E). The compound (E) thusobtained is hydrolyzed, whereby a compound (C) can be obtained. Also, inthe case of this route, the compound (A-2) can be used in place of thecompound (A-1).

A compound (6) which is a preferred example of the compound of thepresent invention can be obtained by reacting the compound (4) thusobtained with a compound (5):

In Formula (5), X² is halogen, and the examples thereof are chlorine,bromine and iodine. X¹, R² and R³ each have the same meanings as thoseof these codes in Formula (2). X¹ and X² may be the same or different.

R¹² and Z¹ in Formula (6) each have the same meanings as those of thesecodes in Formula (4), and R², R³ and X¹ each have the same meanings asthose of these codes in Formula (2).

The compound (4) is readily reacted with the compound (5) to become anester. Hydrogen halides by-produced in the reaction induces sidereactions such as dehydration, addition to a double bond site and thelike, and therefore the reaction is carried out in the coexistence oforganic bases in order to remove the hydrogen halides. The examples ofthe organic bases are pyridine, dimethylaniline, triethylamine andtetramethylurea. The other organic bases may be used as long as they caninhibit the side reactions and allow the reaction to quickly proceed.The most preferred example of the organic bases is triethylamine. Thisreaction is a nucleophilic displacement reaction which quantitativelyproceeds, and a use amount of the compound (5) is preferably 1 to 10times in terms of an equivalent ratio based on the compound (4). Anincrease in a use amount of the compound (5) makes it possible to reactthe whole compound (4) and makes it possible to shorten the reactiontime.

This reaction is usually carried out in an atmosphere of inert gas suchas argon gas and nitrogen gas using a dry organic solvent which isinactive to the raw material. The examples of the organic solvent arecyclic ethers such as tetrahydrofuran and dioxane, aromatic hydrocarbonssuch as toluene and xylene, halogenated hydrocarbons such as methylenechloride and chloroform and carbon tetrachloride. The preferred exampleof the organic solvent is methylene chloride. The reaction temperatureshall not specifically be restricted. However, the above reactionquickly goes on while generating heat, and therefore usually it iscarried out preferably under a low temperature condition. The preferredreaction temperature is 100° C. or lower, and the most referred reactiontemperature is 35° C. or lower. As a matter of fact, the reaction may becarried out while irregularly controlling the reaction temperature. Forexample, employed is a method in which the reaction is carried out whilecooling the reaction system using a dry ice-methanol bath or an ice bathin an initial stage and in which the temperature is then elevated to thevicinity of a room temperature to continue the reaction. The reactiontime shall not specifically be restricted, and usually the intendedsilicon compound can be obtained in 1 to 10 hours.

In the following explanations, the unreacted raw material compounds andthe solvents shall be referred to as “impurities”. If a distillationmethod is applied in order to remove the impurities, the liquid ismaintained under a high temperature condition for long time, andtherefore the intended compound is likely to be decomposed. Accordingly,it is preferably refined by reprecipitation operation in order toefficiently remove the impurities without damaging a purity of thecompound (6). This refining method is carried out in the followingmanner. First, the reaction liquid is dissolved in a solvent dissolvingboth of the compound (6) and the impurities. In this case, a preferredconcentration of the compound (6) is, roughly speaking, 1 to 15% byweight.

Next, such a solvent as not dissolving the compound (6) but dissolvingthe impurities, a so-called precipitant is added to the above solutionto precipitate only the compound (6). A preferred use amount of theprecipitant is 20 to 50 times based on the weight of the solvent usedfor dissolving both of the compound (6) and the impurities. This userange is a rough standard, and as is the case with the foregoingconcentration rage of the compound (6), it may not necessarily fall inthe above range.

The preferred solvent for dissolving the compound (6) is a solventhaving a large dissolving power and a relatively low boiling point. Thepreferred precipitant is a solvent which is compatible with the solventfor dissolving the compound (6) and does not dissolve the compound (6)at all and which dissolves only the impurities and has a relatively lowboiling point. The example of the preferred precipitant is loweralcohols. The particularly preferred precipitant is methanol or ethanol.A repeating frequency of the reprecipitation operation is advisablyraised in order to further elevate the refining degree.

Next, the examples of the compound (1) shall specifically be shown byusing codes defined in Table 1. Examples shown in Table 2 to Table 9 arethe examples of a case in which R¹² is ethyl, 2-methylpropyl,2,4,4-trimethylpentyl, cyclopentyl, cyclohexyl, 3,3,3-trifluoropropyl orphenyl in Formula (6) and in which Z¹ is —(CH₂)₂—, —(CH₂)₃—, —(CH₂)₄—,—(CH₂)₅— or —C₂H₄—O—C₃H₆—. The compound (1) shall not be restricted bythese examples.

The above monomers may be used alone or a plurality thereof may becopolymerized. When copolymerized, they may be random-copolymerized orblock-copolymerized.

Next, a method for subjecting an addition-polymerizable monomer to atomtransfer radical polymerization using the compound (6) as an initiatorand a transition metal complex as a catalyst shall be explained. Theatom transfer radical polymerization method in the present invention isone of living radical polymerization methods, and it is a method forradically polymerizing addition-polymerizable monomers using an organichalide or a halogenated sulfonyl compound as an initiator. This methodis disclosed in J. Am. Chem. Soc., 1995, 117, 5614, Macromolecules,1995, 28, 7901 and Science, 1996, 272, 866.

The preferred example of a transition metal complex used as apolymerization catalyst is a metal complex in which the 7th, 8th, 9th,10th or 11th group element in the periodic table is used as centermetal. More preferred catalyst is a complex of zero-valent copper,monovalent copper, divalent ruthenium, divalent iron or divalent nickel.Among them, the complex of copper is preferred. The examples of amonovalent copper compound are cuprous chloride, cuprous bromide,cuprous iodide, cuprous cyanide, cuprous oxide and cuprous perchlorate.When using the copper compounds, 2,2′-bipyridyl or derivatives thereof,1,10-phenanthroline or derivatives thereof, polyamine(tetramethylethylenediamine, pentamethyldiethylenetriamine,hexamethyltris(2-aminoethyl)amine and the like) or polycyclic alkaloidsuch as L-(−)-sparteine is added as a ligand in order to enhance thecatalyst activity. A tristriphenylphosphine complex (RuCl₂(PPh₃)₃) ofdivalent ruthenium chloride is also suited as the catalyst. When theruthenium compound is used as the catalyst, aluminum alkoxides are addedas an activating agent.

Further, a bistriphenylphosphine complex (FeCl₂(PPh₃)₂) of divalentiron, a bistriphenylphosphine complex (NiCl₂(PPh₃)₂) of divalent nickeland a bistributylphosphine complex (NiBr₂(PBu₃)₂) of divalent nickel arealso suited as the catalyst.

A solvent may be used for the polymerization reaction. The examples ofthe solvent used are hydrocarbon base solvents (benzene, toluene and thelike), ether base solvents (diethyl ether, tetrahydrofuran, diphenylether, anisole, dimethoxybenzene and the like), halogenated hydrocarbonbase solvents (methylene chloride, chloroform, chlorobenzene and thelike), ketone base solvents (acetone, methyl ethyl ketone, methylisobutyl ketone and the like), alcohol base solvents (methanol, ethanol,propanol, isopropanol, n-butyl alcohol, tert-butyl alcohol and thelike), nitrile base solvents (acetonitrile, propionitrile, benzonitrileand the like), ester base solvents (ethyl acetate, butyl acetate and thelike), carbonate base solvents (ethylene carbonate, propylene carbonateand the like), amide base solvents (N,N-dimethylformamide,N,N-dimethylacetamide and the like), hydrochlorofluorocarbon basesolvents (HCFC-141b and HCFC-225), hydrofluorocarbon (HFCs) basesolvents (HFCs having a carbon atom number of 2 to 4, 5 and 6 or more),perfluorocarbon base solvents (perfluoropentane and perfluorohexane),alicyclic hydrofluorocarbon base solvents (fluorocyclopentane andfluorocyclobutane), oxygen-containing fluorine base solvents(fluoroether, fluoropolyether fluoroketone and fluoroalcohol) and water.They may be used alone or two or more kinds thereof may be used incombination.

The polymerization can be carried out as well in an emulsion system or asystem in which a supercritical fluid CO₂ is used as a medium. Thesolvent which can be used shall not be restricted to these examples.

The atom transfer radical polymerization can be carried out underreduced pressure, atmospheric pressure or applied pressure according tothe kind of the addition-polymerizable monomer and the kind of thesolvent. An organic metal complex used in combination or a radicalproduced is likely to be deactivated when brought into contact withoxygen. In such case, the polymerizing speed is reduced, and a goodliving polymer is not obtained. Accordingly, it is important to carryout the polymerization under inert gas atmosphere of nitrogen or argon.In this reaction, dissolved oxygen in the polymerization system has tobe removed in advance under reduced pressure. It is possible to shiftthe reaction system to a polymerization step as it is under reducedpressure after finishing the step of removing dissolved oxygen.Conventional processes can be adopted for the atom transfer radicalpolymerization, and it shall not specifically be restricted by apolymerization process. For example, bulk polymerization, solutionpolymerization, suspension polymerization, emulsion polymerization orbulk-suspension polymerization can be adopted. The polymerizationtemperature falls in a range of 0 to 200° C., and the preferredpolymerization temperature falls in a range of a room temperature to150° C.

A polymer obtained by using the compound (6) as an initiator by theprocess described above can be represented by Formula (7). The polymerrepresented by Formula (7) shall be described as the polymer (7).

P¹ in Formula (7) is a chain of a structural unit obtained bypolymerizing an addition-polymerizable monomer, and the other codes eachhave the same meanings as those of these codes in Formula (6).

Suitable selection of the kind of the addition-polymerizable monomerused makes it possible to control the structure of the compound (7)produced. For example, if the monomer is homopolymerized, silsesquioxaneto which a homopolymer is bonded is obtained. If the plural monomers areadded at the same time and polymerized, silsesquioxane to which a randomcopolymer is bonded is obtained. If used is a method in which themonomers are successively added, for example, a method in which thesecond monomer is added after finishing the polymerization of the firstmonomer to complete the polymerization, silsesquioxane to which a blockcopolymer is bonded is obtained. Repeating of this staged polymerizationusing plural monomers makes it possible to obtain silsesquioxane towhich a multiblock copolymer is bonded. A cross-linked polymer having athree-dimensional network structure can be prepared by allowing amultifunctional monomer, if necessary, to coexist.

Silsesquioxanes to which highly branched type polymers are bonded can beobtained by using in combination a compound having a polymerizablefunctional group as well as a function as an initiator, for example,2-(2-bromopropionyloxy)ethyl (meth)acrylate,2-(2-bromoisobutyryloxy)ethyl (meth)acrylate,2-(2-bromopropionyloxy)styrene and 2-(2-bromoisobutyryloxy)styrene whenpolymerizing a usual addition-polymerizable monomer. Further, combineduse of compounds which are trialkoxysilane, polydimethylsiloxane andsilsesquioxane and which have polymerizable functional groups such as a(meth)acryl group and a styryl group makes it possible to introduce astructural unit containing a silicon atom into the structure of thepolymer. After copolymerized with an addition-polymerizable monomerhaving an initiating group which does not take part in atom transferradical polymerization, for example,1-(2-(4-vinylphenylmethoxy)-1-phenylethoxy)-2,2,6,6-tetramethylpyridine,1-(meth)acryloxy-2-phenyl-2-(2,2,6,6-tetramethyl-1-piperidinyloxy)ethane,1-(4-(4-(meth)acryloyloxyethoxyethyl)phenylethoxy)piperidine andvinylphenylmethyl dithiocarbamate, an addition-polymerizable monomer isfurther polymerized in the other polymerization mode (for example,nitroxyl polymerization and photo initiator-transfer agent-terminatorpolymerization) using the resulting polymer as an initiator, whereby agraft copolymer can be formed.

After copolymerized with a monomer having an oxetanyl group, forexample, 3-ethyl-3-(meth)acryloyloxymethyloxetane,diphenyl-4-thiophenoxyphenylsulfonium hexafluoroantimonate or(4-pentadecyloxyphenyl)phenyliodonium hexafluoroantimonate is added asan initiator to the resulting polymer, whereby it can be subjected tophotocationic polymerization.

Next, a refining method for the polymer (7) shall be explained. Thiscompound is isolated and refined by efficiently removing the unreactedaddition-polymerizable monomer. Various methods are available, and arefining method carried out by reprecipitation operation is preferred.

This refining method is carried out in the following manner.

First, a solvent which does not dissolve the polymer (7) but dissolvesthe unreacted monomer, a so-called precipitant is added to thepolymerization reaction liquid containing the polymer (7) and theunreacted monomer to precipitate only the polymer (7). A preferred useamount of the precipitant is 20 to 50 times based on the weight of thepolymerization reaction liquid described above.

The preferred precipitant is a solvent which is compatible with thesolvent used in polymerization and which does not dissolve the polymer(7) at all but dissolves only the unreacted monomer and has a relativelylow boiling point.

The examples of the preferred precipitant are lower alcohols andaliphatic hydrocarbons. The particularly preferred precipitant ismethanol and hexane. A repeating frequency of the reprecipitationoperation is advisably increased in order to further raise a removingefficiency of the unreacted monomer. This method makes it possible todeposit only the polymer (7) in a poor solvent, and the polymer canreadily be separated from the unreacted monomer by filtering operation.

The transition metal complex which is the polymerization catalystremains in the compound (7) isolated by the method described above, andtherefore problems such as coloring of the polymer, influence on thephysical properties and environmental safety are brought about in acertain case. Accordingly, this catalyst residue has to be removed infinishing the polymerization reaction. The catalyst residue can beremoved by adsorbing treatment using activated carbon.

The examples of adsorbents other than activated carbon are ion exchangeresins (acid, basic or chelate form) and inorganic adsorbents. Theinorganic adsorbents have a character of a solid acid, a solid base orneutrality. They are particles having a porous structure and thereforehave a very high adsorbing ability. It is also one of thecharacteristics of the inorganic adsorbents that they can be used in awide temperature range extending from a low temperature to a hightemperature.

The representative examples of the inorganic adsorbents are silicondioxide, magnesium oxide, silica-alumina, aluminum silicate, activatedalumina, clay base adsorbents such as acid clay and activated clay,zeolite base adsorbents, dawsonites compounds and hydrotalcitescompounds. Zeolite includes natural products and synthetic products, andeither can be used. Kinds such as a crystal form, an amorphous form, anoncrystal form, a glass form, a synthetic product and a natural productare available for silicon dioxide, and silicon dioxide of a powder formcan be used in the present invention regardless of the kind. Theexamples of natural aluminum silicate are pumice, fly ash, kaoline,bentonite, activated clay and diatomaceous earth. Synthetic aluminumsilicate has a large specific surface area and a high adsorbing ability.The hydrotalcites compound is carbonate hydrate of aluminum-magnesiumhydroxide.

The acid adsorbents and the basic adsorbents are preferably used incombination with activated carbon. The examples of the acid adsorbentsare acid clay, activated clay and aluminum silicate. The examples of thebasic adsorbents are activated alumina, the zeolite base adsorbents andthe hydrotalcites compounds each described above. These adsorbents maybe used alone or in a mixture of two or more kinds thereof. The polymer(7) produced by the atom transfer radical polymerization can be refinedby bringing into contact with activated alumina. A commercial productavailable from Aldrich Co., Ltd. can be used as activated alumina. Whenadsorbing treatment is carried out by using activated alumina incombination with the other adsorbents, the adsorbents can be mixed andbrought into contact with the compound, but they may be brought intocontact at the separate steps respectively. When brought into contactwith the adsorbent, the reaction liquid may be used as it is or may bediluted with a solvent. The diluent may be selected from usual solventsonly on the condition that it is not a poor solvent for the polymer. Atemperature for treating with the adsorbent shall not specifically berestricted. The treatment may be carried out usually at 0 to 200° C. Thepreferred temperature range is a room temperature to 180° C. A useamount of the absorbent falls in a range of 0.1 to 500% by weight basedon the weight of the polymer (7). Considering the economical efficiencyand the operability, the preferred range is 0.5 to 10% by weight.

A method of a batch system in which stirring-mixing and solid-liquidseparation are carried out by batch operation can be used forsolid-liquid contact of the absorbent and the polymer liquid. Inaddition thereto, capable of being used is a method of a continuoussystem such as a fixed layer system in which the polymer liquid isallowed to pass through a vessel charged with the adsorbent, a movinglayer system in which the liquid is allowed to pass through a movinglayer of the adsorbent and a fluidized layer system in which theadsorbent is fluidized by a liquid to carry out adsorption. Further, amixing and dispersing operation carried out by stirring can be combined,if necessary, with an operation for elevating the dispersing efficiency,such as shaking of the vessel and use of a supersonic wave. After thepolymer liquid is brought into contact with the absorbent, the absorbentis removed by a method such as filtering, centrifugal separation andsettling separation, and washing treatment is carried out if necessaryto obtain the refined polymer liquid. Treatment by the absorbent may becarried out for the polymer (7) which is the final product, and it maybe carried out for an intermediate product used for producing thispolymer. For example, in the respective polymerizing steps of the blockcopolymer obtained by the atom transfer radical polymerization, thispolymer can be isolated and subjected to adsorbing treatment. Thepolymer (7) subjected to treatment by the adsorbent may be separated bydepositing in a poor solvent or distilling off volatile components suchas the solvent under reduced pressure.

The analytical methods of a molecular weight and a molecular weightdistribution of the polymer (7) produced shall be explained. Usually, amolecular weight of an addition polymer can be measured by gelpermeation chromatography (GPC) using a calibration curve in which alinear polymer such as polystyrene and poly(methyl methacrylate) is usedas a standard sample. A molecular weight and a molecular weightdistribution of the polymer (7) can be analyzed as well by GPC.

The polymer (7) has silsesquioxane at an end part thereof, and thereforeit can readily be decomposed under an acid condition or a basiccondition. That is, an accuracy in molecular weight analysis of apolymer part can further be enhanced by cutting off an addition polymerfrom silsesquioxane and then measuring the molecular weight thereof.Hydrofluoric acid is preferably used when decomposing the polymer (7)under an acid condition. Potassium hydroxide is preferably used whendecomposing the polymer (7) under a basic condition. The polymer (7) canbe decomposed in either of a homogeneous system and a heterogeneoussystem. For example, the silsesquioxane part of the polymer (7) can bedecomposed in a homogeneous mixed system of an organic solvent(tetrahydrofuran, acetonitrile and the like) which can dissolve thepolymer (7) and hydrofluoric acid. The silsesquioxane part can bedecomposed as well in a heterogeneous mixed system of toluene andhydrofluoric acid. In this case, a phase transfer catalyst is preferablyused in combination. The examples of the phase transfer catalyst arebenzyltrimethylammonium chloride, tetramethylammonium chloride,tetrabutylammonium bromide, trioctylammonium chloride,dioctyldimethylammonium chloride, triethylamine and dimethylaniline.When using potassium hydroxide, decomposition can be carried out as wellin a mixed solvent of tetrahydrofuran, ethanol and water.

The addition polymer cut off by the above methods is measured by GPC,whereby a molecular weight of an addition polymer part in the polymer(7) can be determined. It is possible as well to determine a molecularweight of the polymer (7) by using a universal calibration curveobtained from the viscosity and the GPC data. An absolute molecularweight of the polymer (7) can be determined as well by an end groupdetermination method, a membrane osmotic pressure method, aultracentrifugal method and a light scattering method.

A preferred molecular weight of the polymer (7) falls in a range of 500to 1,000,000 for a number average molecular weight in terms ofpolystyrene. The more preferred range is 1,000 to 100,000. However, theupper limit value and the lower limit value in this range do notnecessarily have a specific meaning. The molecular weight distributionfalls preferably in a range of 1.01 to 2.0 in terms of a polydispersity(Mw/Mn).

The molecular weight of the polymer (7) can be controlled by aproportion of the addition-polymerizable monomer to the compound (6)which is an initiator. That is, a theoretical molecular weight of thegraft chain in the polymer (7) can be predicted from a mole ratio of theaddition-polymerizable monomer/the compound (6) and a consumption rateof the monomer using the following calculation equation:Mn=(conversion rate(mole %)of monomer/100)×MW _(M)×mole ratio+MW _(I)In the above calculation equation, Mn is a theoretical number averagemolecular weight; MW_(M) is a molecular weight of theaddition-polymerizable monomer; MW_(I) is a molecular weight of thecompound (6); and the mole ratio is a mole ratio of theaddition-polymerizable monomer to the compound (6).

When intending to obtain a polymer having the number average molecularweight range described above, a mole ratio of the addition-polymerizablemonomer to the compound (6) is controlled to about 2 to about 40,000.The preferred range of the above mole ratio is about 10 to about 5,000.The number average molecular weight can be controlled as well bychanging the polymerization time.

Any method of GPC, ¹H-NMR and gas chromatography can be adopted fordetermining a consumption rate (hereinafter referred to as “conversion”)of the monomer.
